sharpenning discussion

The crock of sand is a very interesting idea.
That might be worth experimenting with.

Another field expedient means of sharpening is using a dollar bill sized sheet of sandpaper. Stores in you wallet, lay it on a flat surface & you're good to go. Thanx to Ed Fowler for that one ;)
 
My knives have always dulled when stuck into sand. I don't see how it will keep them sharp when the grit and grains of sand will be rubbing directly on the edge. Just like cutting food on a ceramic plate will dull because the plate rubs the edge. Why would the sand be any different? Like I said, my personal experiences have been to keep knife edges out of sand.

I would have to argree with Medic1210 sand wears and grinds metal down.It can put shine on metal but not mirrored.A good example of this is crome wheels on my sand buggy and other sand toys.The sand will grind the surface of the metal to a satin finish and wear down the edges of the rims almost to round. Sand can have a devastating effect on metal parts. Another example is at my work.The guy that mixes the mortar in the cement mixer well most have a shovel that they only use to shovel the sand because when you use it to shovel mortar it builds up on it and it picks up weight and with as much sand as these guys have to mix into the mortar every day weight can be a big factor.My point is they use this shovel exclusively for sand and they are anything but sharp in fact the edge will wear down to the right or left depending on which hand is dominate.One of these guys can shovel as much as 5 or 6 yards and up depending on the job and belive me that is alot.One sand truck full can be around ten yards.The trowel I use to lay block/brick with will get razor sharp on one side from scraping it up the face of the block or brick I just set to remove excess mortar.In fact it will get so sharp I rarely have to use my knife on the job and my trowel is 11 to 15 inches long depending on the material being used.Large sharp and crooked as hell after time.So dragging it or rubbing it on block brick or cement will sharpen it and to clean it I will throw sand on the concrete and scrape my trowel through. In my experiance sand has had a negative effect on metal edges...........RB

Ebbtide,


My grandmother kept a crock filled with clean sand in her kitchen. She stored her clean kitchen knives in the sand to keep them sharp. If they started to get dull, she'd take a couple of swipes on the top of the crock, but mostly they stayed honed by just stabbing them into the sand.

Merry Christmas,
